SNPs in contig 254, cathepsin B, a putative gut-specific cysteine protease. Three SNPs were validated by sequencing genomic DNA. Three SNPs in the gene result in one silent change (Leu-Leu), one substitution of a negatively charged amino acid for an aliphatic amino acid (Ala-Glu) and one substitution of an aromatic for an aliphatic amino acid (Leu-Phe) in the green M. persicae lineages (G006 and F001) relative to the red USDA lineage.
